Fluoride is a natural mineral that can safely strengthen teeth to help prevent tooth decay and permanent tooth loss. When a tooth’s surface is weakened by decay, fluoride can be absorbed into the weakened tooth surface to strengthen the enamel. You never stop needing fluoride, and the simple truth is that most people – kids and adults alike – don’t get enough. Many bottled waters do not contain optimal levels of fluoride. And, some types of home water treatment systems can reduce the fluoride levels in water supplies. Using fluoride toothpaste daily is vital for oral care. But you may be shortchanging yourself if you rely on toothpaste alone. Some ACT Fluoride Mouthwash formulas contain the maximum strength of fluoride available without a prescription, making them a simple solution to get the fluoride you need.
